The present disclosure relates to a human figure toy, and more specifically, to a human figure toy having a movable nose.

3. General Background

Throughout the years, a wide variety of toy figures and dolls have been created for entertainment purposes. Such toy figures and dolls have assumed shapes replicating humans, human infants, animals as well as a variety of fictional characters. In their efforts to increase the amusement and entertainment value of such toy figures and dolls, practitioners in the art have created a variety of toy figures and dolls having movable features and articulated bodies and limbs.

U.S. Pat. No. 4,516,951 issued to Saigo et al. sets forth a movable toy animal having a toy figure resembling a bunny or the like supporting a motor driven internal movement mechanism. The movement mechanism is operatively coupled to a pair of movable ears and a movable nose. When operated, the ears and nose undergo a predetermined movement cycle.

U.S. Pat. No. 5,304,087 issued to Terzian et al. sets forth a SOFT STUFFED TOY WITH MANUALLY DRIVEN HEAD, EARS AND/OR TONGUE carried in a flexible sling with the head of the figure exposed. The head includes animatable ears driven by rotation of the head relative to the body. In addition, the protruding movable tongue is driven by an actuator that also provides rotation of the head relative to the body.

While the foregoing described related art devices have, to some extent, improved the art and have, in some instances, enjoyed commercial success, there remains nonetheless a continuing need in the art for evermore improved, interesting and amusing toys having movable components.

DETAILED DESCRIPTION

Referring to FIG. 1, a human figure toy 100 includes a torso 200 and a head 300 attached to the torso 200. The human figure toy 100 also includes two legs and two arms that are attached to the torso 200.

Referring to FIGS. 2 through 5, the head 300 includes a hollow housing 310. The housing 310 is formed to resemble a human face. An aperture 311 is formed on the front side of the housing 310.

As will be better understood from the following description, the toy 100 includes a sensor means 500 that is used for activating a reversible motor. In the embodiment shown in FIGS. 3 and 4, the sensor means 500 can be a pressure sensor. The pressure sensor 500 is mounted on the interior surface of the housing 310. However, when needed, other type of sensors may be used and may be mounted at any suitable portion on the toy 100.

The head 300 includes a support member 320 secured within the housing 310. The support member 320 can be formed by plastic injection molding, in one exemplary fabrication process, and includes two posts 321 (one not shown) onto which a reversible motor 400 is secured. The motor 400 includes a threaded motor shaft 401. Two guide grooves 322 are formed on the support member 320 and extend along a direction that is approximately parallel to the axis of the aperture 311 on the housing 310.

Referring to FIG. 6, the head 300 also includes a nose assembly 330 that is driven by the motor 400. In one embodiment, the nose assembly 330 includes a first rod 340, attachment means 350, a spring 360, and a second rod 370.

Referring to FIG. 7, a threaded bore 341 is formed at one end of the first rod 340 and extends longitudinally. A flange 342 is formed near another end of the first rod 340. The first rod 340 also includes a pair of guide ribs 343 on an outer surface thereof. The guide ribs 343 are formed opposite to each other and extend all the way from the threaded bore end to a side surface 344 on the flange 342.

Referring to FIGS. 8 and 9, the attachment means 350 is used for slidably attaching the second rod 370 to the first rod 340. In the embodiment shown in FIG. 8, the attachment means 350 is of a flanged cylinderical shape and includes a flange portion 351 and a cylindrical portion 352.

A circular hole 353 is formed on the attachment means 350 and extends along the entire length of the attachment means 350. A pair of guide grooves 354 is formed on the inner circumferential surface of the circular hole 353. The guide grooves 354 are positioned opposite to each other and extend along the entire length of the circular hole 353.

A chamber 355 is formed on the flange portion side, extending from a first end surface 356 of the flange portion 351 toward the cylindrical portion 352, which forms two openings 357 on a cylindrical outer surface of the cylindrical portion 352 and a second surface 358 of the flange portion 351. The openings 357 are formed opposite to each other. The attachment means 350 also includes a pair of guide posts 359 formed opposite to each other on an outer circumferential surface of the flange portion 351.

Referring to FIG. 10, the second rod 370 includes a chamber 374 (shown in FIG. 6) that extends longitudinally and is used for receiving the spring 360 therein. A pair of long tabs 371 and a pair of short tabs 372 are formed at the open end of the chamber 374. The long tabs 371 are positioned opposite to each other and angled slightly away from each other. Each of the long tabs 371 includes a hook portion 373 that extends outwardly at a distal end thereof.

After the nose assembly 330 has been constructed, the attachment means 350 is slidably attached to the first rod 340. More specifically, the first rod 340 is received in the circular hole 353 of the attachment means 350 with the guide grooves 354 engaging with the guide ribs 343 respectively. The first rod 340 is pushed against the attachment means 350 by the spring force of the spring 360, and specifically, the side surface 344 of the flange 342 on the first rod 340 engages the first end surface 356 of the flange portion 351 of the attachment means 350.

After the nose assembly 330 has been constructed, the second rod 370 is attached to the attachment means 350 with the two long tabs 371 in a first position and the two short tabs 373 in a second position. More specifically, in the first position, the two long tabs 371 are received in the two openings 357, respectively, with the two hook portions 373 engaging the second end surface 358 of the flange portion 351.

Because the long tabs 371 are slightly outwardly angled, the long tabs 371 are slightly deformed in the first position and a spring force that springs back the long tabs 371 to its original shape pushes the long tabs 371 tightly against edges of the openings 357, thereby preventing the long tabs 371 from disengaging the openings 357.

In the second position, the short tabs 373 contact the surface of the attachment means 350. The movement of the attachment means 350 is thus limited by the long tabs 371 and the short tabs 373, and as a result, the second rod 370 is held in position.

In one embodiment, the spring 360 may be a coil spring and is slightly compressed in the second rod 370. One end of the spring 360 engages one end of the first rod 340. The second rod 370 is thus biased to a furthest position relative to the first rod 340 and can slide along the guide ribs 343 of the first rod 340. During sliding of the second rod 370, the spring 360 is compressed, which is used for absorbing shocks, such as a shock generated when the toy 100 falls with the second rod 370 hitting the ground. As a result, significant damages to the toy 100 can be avoided.

After the nose assembly 330 has been attached to a threaded motor shaft 401 of the motor 400, the second rod 370 extends through the aperture 311 on the housing 310. The guide posts 359 on the attachment means 350 are received in the guide grooves 322 on the support member 320, thereby limiting a rotation of the attachment means 350.

The thread engagement of the motor shaft 400 and the threaded bore 341, the engagement of the guide rib 343 and the guide groove 354, and the engagement of the guide post 359 and the guide groove 322 cooperate to constitute a rotation/translation conversion mechanism. Therefore, a rotation of the motor shaft 401 is converted into translation movement of the nose assembly 330 and the second rod 370 can thus move back and forth.

In one embodiment, the motor 400 is a stepper motor. In this embodiment, the toy 100 also includes a motor control system illustrated in FIG. 10. The motor control system includes a controller 10, a motor drive circuit 20, and a pulse counter 30. The controller 10 is configured for receiving signals from the sensor means 500.

The motor drive circuit 20 receives signals from the controller 10 and provides a series of motor drive pulses to the motor 400 according to the signals from the controller 10. The pulse counter 30 counts the number of the motor drive pulses generated by motor drive circuit 20. When the number of the motor drive pulses reaches a preset value, the pulse counter 30 sends a signal to the controller 10. The controller 10 reverses the motor 400 according to the signal from the pulse counter 30. The nose assembly 330, which is driven by the motor 400, can thus be moved back after reaching a limit position. In this embodiment, the motor 400 can continue running for a predetermined time after which the motor 400 stops running and awaits the next signal from the sensor means 500.
